BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a portable telephone.

2. Description of Related Art

In recent years, not only a telephone call function but also additionalfunctions, such as an electronic mail function for sending and receivingan electronic mail by using an Internet protocol or another uniquenetwork protocol and an Internet function so as to read even WEB havebeen added to a portable telephone. Also, the inclusion of a memory cardserving as a small memory medium in a portable telephone can attain aportable telephone in which an audio signal and a picture signal can berecorded and reproduced as the additional functions. In this way, notonly the original telephone function but also the various additionalfunctions are added to the portable telephone. It is tried to developthe portable telephone having multiple functions.

A relatively large display is typically mounted in the portabletelephone having the thus attained multiple functions. Also, a directionkey and a page scroll key are also mounted for retrieving or selectinginformation displayed on this display.

By the way, even if it is tried to make the display larger, there isalso the limit of the size of the portable telephone itself. Forexample, if an electronic mail is displayed, if WEB is displayed, or ifinformation stored on a memory card is displayed, the display becomesrelatively narrow with respect to the information to be displayed.

In such a case, it is necessary to find out a target information orselect the information by operating a direction key for shifting a focusposition placed as an operation key of the portable telephone in anupper, lower, leftward or rightward direction, or a page scroll key forscrolling upwardly or downwardly displayed information correspondinglyto one page.

However, only from the information displayed on the display, a usercannot find out whether or not the information is located outside adisplay range or whether or not the focus can be shifted from a currentposition. Thus, as a first step, the user operates the direction key oroperates the page scroll key, and thereby checks the existence of theinformation existing outside the display range. However, such anoperation is very troublesome and difficult.

SUMMARY OF THE INVENTION

Accordingly, there has been a need to provide a portable telephone inwhich the operational performances of the direction keys and the likeand the convenience for the user are improved.

In order to solve the above-mentioned problems, a portable telephoneaccording to the present invention is characterized in that it isprovided with: a first operating portion that can be operated indirections opposite to each other; a display for displaying a blockindicative of the first operating portion, predetermined information anda pointer; and a controller for controlling the display so as to shiftthe pointer to a desirable position within the predetermined informationon a screen of the display in accordance with an operation of theoperating portion and also display a mark indicative of a direction towhich the pointer can be shifted and in which the predeterminedinformation exists, adjacently to the block along a shift directionthrough the first operating portion.

A portable telephone according to the present invention furthercomprises a second operating portion for shifting the pointer in adirection vertical to a shift direction of the pointer through the firstoperating portion, wherein the controller controls the display so as todisplay a mark indicative of a direction to which the pointer can beshifted by the second operating portion and in which the predeterminedinformation exists, adjacently to the block along a shift directionthrough the second operating portion.

The first operating portion is a rotatable dial, and the secondoperating portion is two keys, which are arranged closely to each other,on both sides of the rotatable dial.

The main configuration and the main operation of the portable telephone1 having the above-mentioned configuration will be described below.

This portable telephone 1 is the telephone of a wirelessly communicatingsystem, and it is carried by a user. When this portable telephone 1 islocated at a position at which the electric wave transmitted from thebase station can be received, it becomes at a communicable state. Atthis communicable state, after any telephone number is pushed by usingthe dial keys 24, the start key 21 is pushed to start a call and thencall out a partner. Also, at this time of the communicable state, anincoming call from the partner can be received. If there is the incomingcall from the partner, any key is pushed to thereby start the call.

Here, in this portable telephone 1, in order to provide a current stateof a call quality to the user, as shown in FIG. 5, an electric fieldstrength indication 61 indicative of a level of an electric fieldstrength of a received electric wave from the base station is displayedat a predetermined position on a left upper side of the display 15. Theelectric field strength is detected by, for example, thetransmission/reception unit 51. The detected electric field strengthinformation is periodically read by the system controlling unit 57. Thesystem controlling unit 57 carries out the display control of thedisplay 15 on the basis of the read electric field strength information,and provides the electric field strength information to the user. Inthis embodiment, this electric field strength indication 61 isrepresented at approximately four stage levels, such as an excellentlevel, a usual level, a bad level and an incommunicable level, forexample.

Also, this portable telephone 1 has an electronic mail function ofcommunicating with the base station and sending and receiving anelectronic mail by using an Internet protocol.

For example, mail data is sent by displaying a predetermined mail inputscreen, and entering a sentence to be transmitted, and then selecting amail transmission button when it is at the communicable state. Actually,the system controlling unit 57 encodes the inputted electronic mail, andthe transmission/reception unit 51 once sends the encoded mail data tothe base station, and the mail data is transferred from the base stationto a mail server of a partner. Also, when an electronic mail istransferred from the partner to an address of the user, the base stationsends the mail data to the portable telephone 1. The portable telephone1, when receiving the mail data at the time of the communicable state,automatically carries out an incoming mail process, and stores the maildata in an inner memory. Then, the system controlling unit 57 of theportable telephone 1, when obtaining the mail data from the basestation, displays a mail incoming indication 62 at a predeterminedposition on the display 15, as shown in FIG. 5.

Also, this portable telephone 1 has an Internet browsing function ofcommunicating with the base station and viewing or a WEB site on theInternet.

For example, by displaying a browser screen of the Internet and thenentering URL (Uniform Resource Locator) on this screen, communicationwith the base station is carried out, and a data provided through apredetermined URL is downloaded. When an input operation or a selectionoperation is carried out on the basis of the downloaded data, apredetermined data is further downloaded on the basis of theinformation.

In this portable telephone 1, the memory card 4 on which audio data isrecorded can be attached and detached as necessary. It has a function ofrecording and reproducing the audio data, such as an operation forreproducing the audio data recorded on the memory card 4 and anoperation for recording the audio data on this memory card 4.

When the audio data is reproduced, the memory card 4 is inserted intothe insertion slot 32, and a reproduction button is selected. When thereproduction button is selected, the audio data recorded on the memorycard 4 in the insertion slot 32 is decoded by the audio encoder/decoder53, and outputted through the remote controller I/F 56 from the earphonemicrophone 41.

Also, this portable telephone 1 can record audio data received from anexternal computer or an external audio reproduction apparatus.

When audio data is recorded through the external computer, the datainput output terminal 33 and the external computer are connected to eachother by using, for example, an IEEE 1394 interface and the like. Then,an application software on the external computer is used to carry out anoperation for transferring desirable audio data to the memory card 4 (aso-called check-in operation). Accordingly, new audio data can bewritten on the memory card 4. By the way, even an operation for editingthe audio data recorded on the memory card 4 (for example, a deletion ofdata, a rearrangement of a reproducing order or the like) can be carriedout by the external computer.

Also, when audio data is recorded through the external audioreproduction apparatus, the line input terminal 34 and the externalaudio reproduction apparatus are connected through a cable to eachother. Desirable audio data is reproduced by the audio reproductionapparatus, and a recording start command is given to the portabletelephone 1. Thus, a so-called dubbing is started. Then, new audio datacan be written on the memory card 4. The transfer of the signal to theline input terminal 34 may be performed in a form of an analog signal ordigital data. In a case of the analog signal being inputted, the audioencoder/decoder 53 carries out an A/D conversion, and converts the audiosignal into the digital data. Then, the execution of the voice encodingprocess enables the audio data to be written on the memory card 4.

As mentioned above, this portable telephone 1 has the electronic mailfunction, the Internet browsing function and the function of recordingand reproducing the audio data by using the memory card 4, in additionto the usual telephone call function. In this way, there is provided theportable telephone intended to have multiple function.

The respective operation keys and switches will be described below.

When a user operates each of the respective operation keys describedbelow, its control command is sent to the system controlling unit 57.Then, the system controlling unit 57 carries out a control correspondingto a function of each key, as described below.

The rotation push switch 14 is the switch that can be operated by arotating operation and can be operated by a pushing operation.

The rotating operation of the rotation push switch 14 functions as, forexample, the direction key for shifting upwardly and downwardly thepointer, such as the focus, the cursor or the like, which is displayedon the display 15. The focus is, for example, the display to specify onepiece of information (one icon, one menu title, one song title or thelike) from information groups (for example, a plurality of icons, menudisplays, list displays or the like) displayed on the display 15.Usually, the display of the specified information is highlighted orreversing displayed. This rotation push switch 14 is mounted at thecenter in the short side direction on the operation surface 11.Moreover, the direction of the rotating operation is the upper and lowerdirections (the longitudinal direction) of the operation surface 11.Thus, when the focus is shifted upwardly or downwardly, the shift of thefocus on the display screen is parallel to the operation of an operatingfinger. Also, the operating finger is located oppositely to the displayscreen. Hence, the coincident feeling between the operational feelingand the screen operation is given to the user. Moreover, the buttonssuch as the upper and lower keys and the like make the operation easy.

The pushing operation of the rotation push switch 14 has the function asthe so-called soft key. The soft key is a key in which an action whenthe button is pushed is changed in a programmable manner on the basis ofthe menu content and the information displayed on the display 15. Thissoft key is designed such that a content of a function selected when thebutton is pushed is displayed on the display 15 and the user canrecognize the actual content of the action when this button is currentlypushed. Concretely, the function selected when this rotation push switch14 is pushed is displayed as a central soft key function indication 63,at a center on a lower side of the display screen of the display 15, asshown in FIG. 5.

The left soft key 16 functions as the above-mentioned soft key. Afunction selected when this left soft key 16 is pushed is displayed as aleft soft key function indication 64, at a left hand position on a lowerside of the display screen of the display 15, as shown in FIG. 5.

The right soft key 17 also functions as the above-mentioned soft key. Afunction selected when this right soft key 17 is pushed is displayed asa right soft key function indication 65, at a right hand position on alower side of the display screen of the display 15, as shown in FIG. 5.

The leftward direction key 18 functions as a shift key to shift thefocus and the cursor displayed on the display 15 to a leftwarddirection.

The rightward direction key 19 functions as a shift key to shift thefocus and the cursor displayed on the display 15 to a rightwarddirection.

The start key 21 functions as a key to start a telephone call.

The clear key 22 functions as a key to switch a display state of thedisplay screen to an initial display menu screen, or to clear inputinformation.

The end key 23 functions as a key for terminating a call or a powersupply unit key to carry out an end function of a telephone outgoing andturn on and off a power supply of the portable telephone 1.

The dial keys (0 to 9, and * and #) 24 function as the input keys fornumerals 0 to 9 and symbols * and #. In addition, various characters areallocated thereto. Each of them functions as a character input key at atime of a character input of an electronic mail or the like. The kind ofthe allocated character is switched depending on a later-describedcharacter input mode setting screen. The kinds of the allocatedcharacters include, for example, a kanji (Chinese character), adouble-byte (full size) kana (Japanese character), a double-byte (fullsize) alphabet, a double-byte (full size) numeral, a double-byte (fullsize) symbol (character letter or pictorial letter), a standard sentenceformat, a single-byte (half size) kana, a single-byte (half size)alphabet, a single-byte (half size) numeral, a single-byte (half size)of symbol (character letter or pictorial letter) and the like.

The manner key 25 functions as a key to set the manner mode of removingan incoming tone via a voice or sound.

The memo key 26 functions as a key to store a telephone number and thelike during a call service.

By the way, the manner key 25 and the memo key 26 also have a page feedfunction of scrolling information displayed on the display 15,correspondingly to one page. In a case of other than making a call, forexample, writing an electronic mail or browsing a WEB, the manner key 25functions as an upward page feed key, and the memo key 26 functions as adownward page feed key. Hereafter, the manner key 25 is referred to asan upward page feed key 25, and the memo key 26 is referred to as adownward page feed key 26.

(Rearrangement of Song Order)

An operation for rearranging an order of songs (music pieces) of audiodata recorded on the memory card 4 will be described below.

In this portable telephone 1, it is possible to rearrange and edit theorder of songs (music pieces) of the audio data recorded on the memorycard 4. By the way, the music order described here implies the numberorder of the numbers given to respective information units, for example,such as the numbers of tracks or the numbers of files recorded in amanagement information of a record medium. Typically, it corresponds toa reproducing order in a case of a continuous reproduction. Thus, evenif the song order is rearranged, the actual content (audio data)recorded on the memory card 4 is not rewritten. The file number and thetrack number managed as the management information, or a link relationbetween songs (music pieces) or the like are rewritten.

At first, in the portable telephone 1, the audio data is reproduced.Once it is interrupted, a display screen is displayed as shown in FIG.6A. If the left soft key 16 is pushed while this screen is displayed and“Function” is selected, an edition mode selection screen is displayed asshown in FIG. 6B.

On this edition mode selection screen, the rotation push switch 14 isrotationally operated to shift a focus F upwardly and downwardly so thatthe focus F is located at a position of “Song Rearrangement”. Insuccession, when the rotation push switch 14 is pushed and operated toselect “Selection”, a title list display screen is displayed as shown inFIG. 6C.

On this title list display screen, the titles and the title numbers tospecify the songs (pieces of music) recorded on the memory card 4 arearranged in the upward and downward directions based on a song ordercurrently being registered, and displayed in a form of list.

The focus F is firstly shifted from this state of the title list displayscreen to a position of a title of a song (music piece) desired to beshifted. At this time, the focus F is shifted by rotationally operatingthe rotation push switch 14 since the title list is arranged in theupward and downward directions. Here, as shown in FIG. 7A, it is assumedthat the focus F is shifted to a position of “Title A”. In succession,if the rotation push switch 14 is pushed and operated to select“Selection”, “Title A” is selected as shown in FIG. 7B.

Here, in a case where the left soft key 16 is pushed when the screenshows the state at which this “Title A” is selected, and “Return” isselected, the operational flow returns back to a display screen in whichthe reproduction of the audio data is once stopped, as shown in FIG. 7E.

On the other hand, in a case where the rotation push switch 14 isrotationally operated when the screen shows the state at which this“Title A” is selected, the title character letters of “Title A” togetherwith the focus F are shifted upwardly and downwardly on the title list.Then, the focus F and the title character letters of “Title A” areshifted to a position at which the rearrangement on the title list isdesired. Here, as shown in FIG. 7C, it is assumed that they are shiftedto a position between “Title D” and “Title E”. In succession, therotation push switch 14 is pushed and operated to select“Determination”. Then, as shown in FIG. 7D, this leads to the state thatthe selected title is shifted to the desired position, which results inthe completion of the rearrangement of the title list. Moreover, ifanother title is further desired to be shifted, the focus F is shiftedfrom this screen to a position of a title of a song (music piece)desired to be shifted. At that position, the rotation push switch 14 ispushed and operated to select “Selection”. Such operations enable theplurality of titles to be continuously shifted.

When the shifts of the titles are all completed, “Completion” isselected by pushing the right soft key 17 from a state of FIG. 7D. Whenthis “Completion” is selected, the system controlling unit 57 rewritesthe management information of the memory card 4 in accordance with theorder of the title list currently being displayed, and also returns thedisplay screen back to the screen in which the reproduction of the audiodata is once stopped, as shown in FIG. 7E.

The above-mentioned processing procedure will be described below withreference to a flowchart in FIG. 8.

The title list in which the plurality of titles to specify the songs ormusic pieces recorded on the memory card 4 are arranged in accordancewith the recording order is displayed (Step S11). In succession, byoperating the rotation push switch 14 in the rotating direction, thefocus is shifted to a title position of a song desired to be shifted. Atthe title position, the rotation push switch 14 is operated in thepushing direction, and its title is selected (Step S12). Next, the titleselected by operating the rotation push switch 14 in the rotatingdirection is shifted to any position on the list (Step S13). Then, atthe title position, the rotation push switch 14 is operated in thepushing direction to thereby determine the shift destination of thetitle (Step S14). After the determination of the shift destination ofthe title, it is possible to operate the rotation push switch 14 in therotating direction to thereby select a title of a next song or musicpiece desired to be shifted. When the shifts of the titles are allcompleted, the display of the title list is ended, and the order ofrecording the songs recorded on the memory card 4 is rewritten inaccordance with the title list order (Step S15).

As mentioned above, in the portable telephone 1, the editing work can bevery easily carried out by rearranging the recording order of the audiodata recorded on the memory card 4 in accordance with such anoperational procedure.

By the way, the example of rearranging the audio data recorded on thememory card 4 has been described as mentioned above. However, in thisprocedure, the target for the rearrangement is not limited to the audiodata. It may be applied to any information, if it is the information todefine a recording order, for example, such as a picture data, acomputer data, a telephone number list, an address list and the like.Also, the memory card 4 is exemplified as a recording medium. However,it may be any medium if it is a rewritable recording medium, such as theinner memory of the portable telephone 1, MD, and DVD-RAM.

(Switching of Character Input Mode)

An operation for switching a character input mode will be describedbelow.

In the portable telephone 1, a plurality of character kinds are assignedto the dial keys 24. Any character kind of a character can be entered byswitching the character input mode.

In the portable telephone 1, when the right soft key 17 is pushed toselect “Mode” when a character input screen is displayed at the time ofwriting an electronic mail or the like, a character input mode selectionscreen is displayed as shown in FIG. 9A.

On this character input mode selection screen, all the character kindsassigned to the dial keys 24 are displayed on a list of two columns. Thecharacter kinds assigned to the dial keys 24 include, for example, akanji (Chinese character), a double-byte (full size) kana, a double-byte(full size) alphabet, a double-byte (full size) numeral, a double-byte(full size) symbol (character letter or pictorial letter), a standardsentence format, a single-byte (half size) kana, a single-byte (halfsize) alphabet, a single-byte (half size) numeral, and a single-byte(half size) symbol (character letter of pictorial letter). On thischaracter input selection screen as shown in FIG. 9A and FIG. 9B, akanji (Chinese character) (top column), a double-byte kana (second uppercolumn), a double-byte alphabet (third upper column), a double-bytenumeral (third lower column), a double-byte symbol (character letter orpictorial letter) (second lower column), a standard sentence format(bottom column) are displayed in the left column of the list, and asingle-byte kana (second upper column), a single-byte alphabet (thirdupper column), a single-byte numeral (third lower column), and asingle-byte symbol (character letter of pictorial letter) (second lowercolumn) are displayed in the right column of the list.

On this character input mode selection screen, the rotating operation ofthe rotation push switch 14 enables the focus F to be cyclically shiftedin an order of a kanji→a double-byte kana→a double-byte alphabet→adouble-byte numeral→a double-byte symbol (character)→a standard sentenceformat→a single-byte kana→a single-byte alphabet→a single-byte numeral→asingle-byte symbol (character)→a kanji→a double-byte kana and so on, asshown in FIG. 9B. Also, pushing the leftward direction key 18 or therightward direction key 19 causes the focus F to be shifted between theleft and right columns.

When this character input mode selection screen is displayed, therotation push switch 14 and the direction keys 18, 19 that are operatedas mentioned above are used to shift the focus to the character kinddesired to be used. Then, when the rotation push switch 14 is pushed andoperated to select “Selection”, the operational flow returns back to thescreen to write the electronic mail or the like. Thus, it is possible toenter the character set of the selected character kind.

As mentioned above, in the portable telephone 1, when the characterinput mode is operationally set on a character write screen, thecharacter input mode selection screen in which all the character kindsare displayed is displayed. The selection of a character kind based onthis character input mode selection screen enables the character of anycharacter kind assigned to the dial keys 24 to be entered.

For this reason, in the portable telephone 1, the character input modecan be easily selected without any troublesome work such as an operationfor pushing the mode set buttons, one by one, and then switching thecharacter input mode.

By the way, on the character input mode selection screen, it may bedesigned to display only the character kind that can be entered at thattime or select only the character kind that can be entered at that time.For example, when an electronic mail address or URL is entered, it ispossible to design the character input mode selection screen so thatonly a half size of alphabet and a half size of numeral can be selected.

(Guidance Display)

A guidance display of a shiftable direction of a focus or the like and aguidance display of a page feed key will be described below.

In this portable telephone 1, a direction key guidance display iscarried out for indicating whether or not the rotation push switch 14can be rotationally operated and whether or not the leftward directionkey 18 and the rightward direction key 19 can be operated. That is, thedirection key guidance display indicates whether or not the pointer suchas the focus, the cursor and the like can be effectively shiftedupwardly and downwardly by rotationally operating the rotation pushswitch 14 and whether or not the pointer such as the focus, the cursorand the like can be effectively shifted in the leftward and rightwarddirections by operating the leftward direction key 18 and the rightwarddirection key 19.

This direction key guidance display is constituted by an upwardlyshiftable mark 71, a downwardly shiftable mark 72, a leftwardlyshiftable mark 73 and a rightwardly shiftable mark 74, as shown in FIG.10.

In other words, the upwardlyshiftable mark 71 is displayed, for example, if the focus F can beshifted in a direction of an arrow “a” in FIG. 10 (i.e., for example, ifa selectable information exists at a further upper position of thefocused information), and it is not displayed if the focus F can not beshifted in the direction of the arrow “a” in FIG. 10 (i.e., for example,if the selectable information does not exist at the further upperposition of the focused information.

The downwardly shiftable mark 72 is displayed if the rotation pushswitch 14 can be downwardly operated, and it is not displayed if therotation push switch 14 cannot be downwardly operated. In other words,the downwardly shiftable mark 72 is displayed, for example, if the focusF can be shifted in a direction of an arrow “b” in FIG. 10 (i.e., forexample, if a selectable information exists at a further lower positionof the focused information), and it is not displayed if the focus Fcannot be shifted in the direction of the arrow “b” in FIG. 10 (i.e.,for example, if the selectable information does not exist at the furtherlower position of the focused information).

The leftwardly shiftable mark 73 is displayed if the leftward directionkey 18 can be operated in the leftward direction, and it is notdisplayed if the leftward direction key 18 cannot be operated in theleftward direction. The leftwardly shiftable mark 73 is displayed, forexample, if the focus F can be shifted in a direction of an arrow “c” inFIG. 10 (i.e., for example, if a selectable information exists at afurther leftward position of the focused information or if there is ascreen of an upper hierarchy of the selected information), and it is notdisplayed if the focus F can not be shifted in the direction of thearrow “c” in FIG. 10 (i.e., for example, if the selectable informationdoes not exist at the further leftward position of the focusedinformation or if there is not the screen of the upper hierarchy of theselected information).

The rightwardly shiftable mark 74 is displayed if the rightwarddirection key 19 can be operated in the rightward direction, and it isnot displayed if the rightward direction key 19 cannot be operated inthe rightward direction. That is, the rightwardly shiftable mark 74 isdisplayed, for example, if the focus F can be shifted in a direction ofan arrow “d” in FIG. 10 (i.e., for example, if a selectable informationexists at a further rightward position of the focused information or ifthere is a screen of a lower hierarchy of the selected information), andit is not displayed if the focus F can not be shifted in the directionof the arrow “d” in FIG. 10 (i.e., for example, if the selectableinformation does not exist at the further rightward position of thefocused information or if there is not the screen of the lower hierarchyof the selected information).

(Answer Rejection During Music Reproduction)

The process of the portable telephone 1 when there is an incoming callfrom a partner during an audio reproduction will be described below withreference to display screens of FIGS. 15A, 15B and a flowchart of FIG.16.

When the portable telephone 1 receives an incoming call from a partnerduring an audio reproduction (Step S21), a display screen is displayedas shown in FIG. 15A. At this time, if any key except the left soft key16 is pushed (Step S22), the incoming call is received to start a call.Here, if the call is started, the audio reproduction is transientlysuspended (Step S23). Also, when there is the incoming call, and theleft soft key 16 is pushed (Step S22), a menu is displayed as shown inFIG. 15B (Step S24).

At this step S24, a menu display is carried out for indicating “Forwardto Answer Service”, “Incoming Call Forwarding”, “Answer Holding” and“Answer Rejection”.

In succession, in accordance with this menu display, the rotation pushswitch 14 is rotationally operated to then select any one of the menus(Steps S25, S26).

Here, if “Forward to Answer Service” is selected, a process is carriedout for forwarding the telephone call from the partner to a telephoneanswer service station installed in the base station. If “Incoming CallForwarding” is selected, a process is carried out for forwarding thetelephone call from the partner to another telephone number. Also, if“Answer Holding” is selected, a state at which the incoming call fromthe partner is held is maintained (namely, the calling state is held).And, if “Answer Rejection” is selected, a process is carried out fordisconnecting the telephone call from the partner.

In the portable telephone 1, if such a menu selection is done, anoperation for rejecting a call is carried out correspondingly to theselection. At this time, the audio reproduction is continued (Step S27).

As mentioned above, in the portable telephone 1, if there is theincoming call during the audio reproduction, the rejection of the callis done depending on the operational input. Due to this mechanism, inthe portable telephone 1, the simple operation enables the reproductionto be continued if there is the incoming call during the audioreproduction.

(Emergent Telephone Call in Case of Outgoing/Incoming Call Off Mode)

In this portable telephone 1, an outgoing/incoming call off mode can beset so as not to transmit and receive an electric wave by stopping theoperation of the transmission/reception unit 51. When thisoutgoing/incoming call off mode is selected, for example, on the menuscreen, the system controlling unit 57 stops a protocol operation of thetransmission/reception unit 51, and perfectly stops transmitting andreceiving the electric wave to and from the base station. Such settingof the outgoing/incoming call off mode can stop only the transmissionand reception of the electric wave without turning off the power supplyof the main body. Thus, it can be set at the state that the functionsexcept the telephone function can be used. Hence, for example, althoughthe telephone function cannot be used at this outgoing/incoming call offmode, it is possible to carry out the input operation of the characterof the electronic mail, the recording and the reproduction of the music,and the like other operations.

Here, a process when a telephone number input is carried out in a caseof this outgoing/incoming call off mode is set being described withreference to FIG. 17.

If the outgoing/incoming call off mode is set, when the dial key 24 ispushed and a telephone number is inputted (Step S31), the systemcontrolling unit 57 displays the pushed telephone number on the display15 (Step S32).

In succession, when the start key 33 is pushed (Step S33), the systemcontrolling unit 57 judges whether or not its telephone number inputtedis one of emergency phone call numbers (for example, in a case of Japan,110 for police, 118 for coast guard and 119 for fire station and/orambulance) or a pre-registered predetermined telephone number (StepS34). By the way, the registered telephone number is desired to bedifferent from a usual address registration, and it is desired to be atelephone number specially registered for an emergency.

If the telephone number inputted is not one of the emergency phone callnumbers or the pre-registered telephone number, the outgoing call isstopped, and the outgoing/incoming call off mode is maintained in itsoriginal state (Step S35). That is, a phone call cannot be made.

On the other hand, if it is one of the emergency phone call numbers orthe pre-registered telephone number, the system controlling unit 57cancels the outgoing/incoming call off mode, and then actuates theprotocol process of the operation of the transmission reception unit 51(Step S36).

In succession, when the protocol process of the operation of thetransmission/reception unit 51 is started, the transmission/receptionunit 51 starts an operation for capturing a base station.

When the transmission/reception unit 51 captures the base station, thetransmission/reception unit 51 starts a process for transmitting aninput telephone number (Step S38).

As mentioned above, in this portable telephone 1, even if it is set atthe outgoing/incoming call off mode at which the transmission/receptionof the electric wave is stopped and the outgoing/incoming of a call isnot done, if a phone call of emergency or a preliminarily registeredphone call is made, a call can be started without canceling operation ofthe outgoing/incoming call off mode by the user. Thus, it is possible toimmediately make a report or make a call.

(Automatic Outgoing/Incoming Call Off During Recording Audio Data)

As mentioned above, in the portable telephone 1, the audio data inputtedfrom the line input terminal 34 or the data input/output terminal 33 canbe recorded on the memory card 4. A process when there is a request forrecording audio data in the portable telephone 1 is described withreference to FIG. 18.

At first, when the power supply of the portable telephone 1 is turned onand there is the request for recording the audio data (Step S41), thesystem controlling unit 57 obtains information of a protocol operationstate of the transmission/reception unit 51, and stores it in a memory(Step S42).

The system controlling unit 57 judges whether or not the protocol forthe transmission/reception of the transmission/reception circuit 51 iscurrently operated (Step S43). If the protocol is operated, theoperational flow proceeds to step S44. If it is not operated, theoperational flow proceeds to step S45.

The system controlling unit 57, if the protocol of thetransmission/reception circuit 51 is operated, stops the operation ofthe protocol of this transmission reception circuit 51, and sets at theportable phone 1 at the outgoing/incoming call off mode in which theoutgoing/incoming of the telephone call is not carried out.

The system controlling unit 57 starts the operation for recording theaudio data (Step S45). Thus, the operation for recording the audio dataat this step S45 is always carried out at the state at which it is setat the outgoing/incoming call off mode.

The system controlling unit 57, if there is a record stop request (StepS46), obtains a protocol operation state of the transmission/receptioncircuit 51 prior to the actuation of the recording operation stored inthe memory at the previous step S42 (Step S47).

It judges whether or not the protocol is under operation, from theinformation read out at the step S47 (Step S48). If the protocol isunder operation, the operational flow proceeds to step S49. If it is notunder operation, the process is ended.

Next, the system controlling unit 57, if the protocol of thetransmission/reception circuit 51 is under operation, starts theoperation of the protocol of the transmission/reception circuit 51 (StepS49). Then, the series of audio recording processes is ended.

As mentioned above, in the portable telephone 1, the interference in therecording operation caused by the incoming call can be avoided byautomatically setting it at the outgoing/incoming call off mode, ifthere is the recording operation request.

(Display of Electric Field Strength in Remote Controller)

In the portable telephone 1, the remote controller unit 3 is mounted asmentioned above. The remote controller 42 in this remote controller unit3 carries out a remote control for reproducing the audio data recordedon the memory card 4 and a remote control for the function of the mainbody of the portable telephone.

Such process for displaying electric field strength through the remotecontroller 42 will be described below with reference to a flowchartshown in FIG. 19.

If the user requests a display of electric field strength (Step S61),the remote controller controlling unit 46 of the remote controller 42sends a report request of the electric field strength to the systemcontrolling unit 57 (Step S62).

The system controlling unit 57 of the main body 2 sends electric fieldstrength information currently being held (the information fordisplaying the electric field strength indication 61) and a timeouttimer value to the remote controller 42 (Step S63).

When receiving the report from the system controller 57, the remotecontroller controlling unit 46 of the remote controller 42 judgeswhether or not any indication is currently displayed on the display unit44 of the remote controller 42 (Step S64). If any indication isdisplayed on the display unit 44, the operational flow proceeds to stepS65. If it is not displayed, the operational flow proceeds to step S66.

The remote controller controlling unit 46 of the remote controller 42transiently saves the information currently being displayed on thedisplay unit 44 (Step S65).

The remote controller controlling unit 46 of the remote controller 42displays the electric field strength on the display unit 44, based onthe electric field strength information sent out from the systemcontrolling unit 57 of the main body 2 (Step S66). In the embodiment,the electric field strength information is displayed on the display unit44 at approximately four stage levels, for example, such as an excellentlevel, a usual level, a bad level and an impossible communication.However, the indication is not limited to such four-stage-level display,and any other way for indicating the electric field strength may beemployed.

The remote controller controlling unit 46 of the remote controller 42actuates a timer (Step S67). The actuated timer carries out countinguntil a counted value reaches the timeout timer value sent out from thesystem controlling unit 57 of the main body 2. If the counting is ended,a timer event is generated.

If the timer event is generated from the timer (Step S68), The remotecontroller controlling unit 46 of the remote controller 42 judgeswhether or not there is the save information transiently saved at thestep S65 (Step S69). If there is the save information, the operationalflow proceeds to step S70. If there is not the save information, theoperational flow proceeds to step S71.

In succession, if there is the save information, the remote controllercontrolling unit 46 of the remote controller 42 again displays the saveinformation, and ends the process (Step S70). Also, the remotecontroller controlling unit 46 of the remote controller 42, if there isnot the save information, removes the indication on the display unit 44,and ends the process (Step S71).

By the way, it may be designed that the timeout timer value is not sentout from the main body 2 and that it is set in advance on the remotecontroller side.

As mentioned above, the portable telephone 1 has the remote controllerunit 3 separately mounted from the main body 2, and the electric fieldstrength information is displayed on this remote controller unit 3. Thismechanism of the portable telephone 1 enables the electric fieldstrength of the received electric wave to be simply and convenientlychecked by the user. For example, even if the main body 2 of theportable telephone is kept in a bag or the like, the electric fieldstrength information is displayed on, for example, the remote controllerunit 3. Thus, the user can check a current electric wave reception statevery simply without especially taking out the main body 2 from the bagor the like to check the status. Also, the electric field strengthinformation is not always displayed on the remote controller unit 3.That is, it is displayed, as necessary, in accordance with the operationfrom the user. Hence, it is possible to effectively use the displayregion placed on the remote controller unit 3.

(Display of Incoming Call on Remote Controller)

In the portable telephone 1, the remote controller unit 3 is disposed asmentioned above. The remote controller 42 of this remote controller unit3 carries out the remote control for reproducing the audio data recordedon the memory card 4 and the remote control to the function of the mainbody 2 of the portable telephone.

A process for displaying a mail incoming by using such a remotecontroller 42 will be described below with reference to a flowchartshown in FIG. 21.

When automatically receiving a mail data from the base station (StepS81), the system controlling unit 57 of the main body 2 sends out a mailincoming display report and a timeout timer value to the remotecontroller 42 (Step S82).

When receiving the report from the system controller 57, the remotecontroller controlling unit 46 of the remote controller 42 judgeswhether or not any indication is currently displayed on the display unit44 of the remote controller 42 (Step S83). If any indication isdisplayed on the display unit 44, the operational flow proceeds to stepS84. If it is not displayed, the operational flow proceeds to step S85.

The remote controller controlling unit 46 of the remote controller 42transiently saves the information currently being displayed on thedisplay unit 44 (Step S84).

In accordance with a mail incoming report sent out from the systemcontrolling unit 57 of the main body 2, the remote controllercontrolling unit 46 of the remote controller 42 displays the mailincoming indicative of the presence of the mail incoming (Step S85).This incoming indication is displayed, for example, such as “You've GotMail”, as shown in FIG. 22.

The remote controller controlling unit 46 of the remote controller 42actuates the timer (Step S86). Then, the actuated timer carries outcounting until a counted value reaches the timeout timer value sent outfrom the system controlling unit 57 of the main body 2. When the countis ended, the timer event is generated.

When the timer event is generated from the timer (Step S87), the remotecontroller controlling unit 46 of the remote controller 42 judgeswhether or not there is the save information transiently saved at thestep S84 (Step S88). If there is the save information, the operationalflow proceeds to step S89. If there is not the save information, theoperational flow proceeds to step S90.

In succession, when there is the save information, again displays thesave information, the remote controller controlling unit 46 of theremote controller 42, and ends the process (Step S89). Also, the remotecontroller controlling unit 46 of the remote controller 42, when thereis not the save information, removes the indication on the display unit44, and ends the process (Step S90).

By the way, it may be designed that the timeout timer value is not sentout from the main body 2 and that it is set in advance on the remotecontroller side.

As mentioned above, the portable telephone 1 has the remote controllerunit 3 separately mounted from the main body 2, and the fact of theincoming of the electronic mail is displayed on this remote controllerunit 3.

This mechanism of the portable telephone 1 which is a characteristicfeature of the invention enables the fact of the incoming of theelectronic mail to be quickly reported to the user. Also, the user caneasily recognize the fact of the incoming of the electronic mail. In theportable telephone 1, for example, even if the main body 2 is kept in abag or the like, the mail incoming is displayed on, for example, thedisplay of the remote controller unit 3. Thus, the user can recognizethe fact of the incoming of the electronic mail quickly and easilywithout especially checking the main body 2.
